Chandler got flack for his name for what seems like the entirety of "Friends." Whether he was being teased for his "uncool" first name or hilariously called Miss Chanandler Bong on his TV Guide deliveries, it was common knowledge that Chandler's name was an easy target for jokes. The joke went even further in Season 8, when we learned that Chandler also had an embarrassing middle name.
In Season 8 Episode 5, Ross discovered that one of Chandler's coworkers called Chandler by the name of Toby, and Chandler never got the courage to correct him — even after five years. When Ross tried to convince Chandler that he had to tell the guy the truth, Chandler brushed it off and said "So he calls me Toby once in a while — what's the big deal? Could be worse. It's not like he's calling me Muriel." Chandler then froze, realizing that he just confessed his true middle name for the first time, before Ross connected the dots in surprise.
That's right — after knowing each other for years, Ross never knew the truth behind Chandler's full name: Chandler M. Bing. Ross's reaction was hilarious, as was his line "Chandler Muriel Bing. Boy, your parents never even gave you a chance, did they?" The revelation was so out of the blue, and the name was so random and old lady-like, that it remains one of the funniest revealed secrets of the series.
